The company, considered by analysts as one of the restaurant industry's best operators, said it now expects same-restaurant sales to increase in the high-single-digit percentage range, excluding any menu price increases.

Its prior forecast was for an increase in the low-single-digit percentage range.

The fast-growing burrito chain also reiterated its plans to open 180-195 new Chipotle restaurants in 2014, more than ever before.

Health conscious consumers frequent Chipotle, which is known for using antibiotic-free meats and organic produce when possible. It was the first major U.S. restaurant chain to announce plans to remove food ingredients containing genetically modified organisms, or GMOs, from its supply chain.

The company's net income rose to $83.1 million, or $2.64 per share, in the first quarter ended March 31, from $76.6 million, or $2.45 per share, a year earlier.

Sales at restaurants open at least 13 months, a closely watched measure of industry performance, rose 13.4 percent, accelerating from the 9.3 percent it posted in the prior quarter.
